JP aka Joseph Philip is Dope :) He make sures you are doing exercise the right way and also make sures you are WET with sweat by the time you leave Boot Camp.Keep up the good work JP 🤝👏Guys let me tell you fitness is like growing a small plant. you have to take care of the plant water it daily and put some fertilizer if need and slowly grow.This is the most friendly gym I ever attended. Do not give up hope and keep trying. 80% of it is your diet, reduce carbs and increase protein AND most importantly do only what your body can support SAFELY. for me SAFETY is more important any thing out there.Important Tip : Please measure your success by doing body composition test, biweekly or once a month. I use Inbody scan. Its available in Max Muscle Nutrition shop. I worked hard in crossfit but did not maintain nutrition I DO NOT want others to make the same mistake.I Hope crossfit Union city also purchases one In body scan to help customers to see their progress.

I joined One World in August 2021. I started attending the evening bootcamp classes. On my first day, coaches Jp and Mo introduced me to the class. Everyone in the class was very welcoming, and the coaches observed me to ensure I was doing the movements safely. I felt very comfortable on my first day. During my time in bootcamp, I learned new skills and developed the confidence to do movements I found intimidating before such as box jumps (shout out to Coach Lalyk for helping me build that confidence).Eventually after a few months of bootcamp, I wanted to do more barbell movements and tried CrossFit. The CrossFit WODs are thoughtfully programmed. For example, Coach Ron programmed a multiple week cycle intended for upper body strength development. I didn't finish the cycle due to reasons unrelated to CrossFit (mostly because I was focusing on another sport I'm participating in), but I understood and appreciated his method. The coaches are experienced in the CrossFit movements, and I've observed they are supportive of the members' goals and journeys.At this moment, I switched to Olympic weightlifting due to a change in my goals. The weightlifting program has excellent coaching--Coach Yatsek encourages team spirit and to have fun lifting. The atmosphere is supportive, and I enjoy going to every training session.Almost two years later after stepping into OW, I feel physically great and have made some awesome friends. If you are looking for a place to feel welcomed as you pursue your wellbeing goals, come check out One World.

If you're looking for a CrossFit gym, look no further because CrossFit OneWorld is the one. If you're new to fitness like I was don't worry because all the coaches are very supportive. They will always demonstrate a modified or different version of a movement. The members of CrossFit OneWorld are all different ages, size, weight, etc and come from all walks of life. This gym is phenomenal and has an even better community. If I could give more than 5 stars I would.

Look no further if you are looking for a "community" of great coaches and people to achieve your fitness goals. When most of us call "One World" our second family, we mean it.I love the flexibility of going to classes at different times, depending on my schedule. One World offers a variety of classes to pick from - Bootcamp, CrossFit, Karv, HIIT, Master's class ( for seniors), and yoga.Each coach is unique, and they program workouts that will challenge and push you to become a better athlete. Coaches are warm, welcoming, and knowledgeable; they understand your weaknesses and limitations and help you get better accordingly. That added personal touch is what I like the most about One World. They genuinely care—the best CrossFit place in the tri-city area. I highly recommend One World to anyone, no matter where one is on their fitness journey.

CrossFit One World & Self Defense is an impressive gym. It provides a positive environment where everyone feels welcome, and no one is made to feel intimidated. I have been to gyms with very toxic environments. This gym is the antithesis of that. There is a feeling of community, and everyone is here to do something positive for themselves, not to sit around judging others. I love the "Check Your Ego at the Door" sign at the front door. This gym offers a wide selection of programs. One would certainly find a program that is a good match for them. All of the personnel are friendly and helpful. I highly recommend CrossFit "One World & Self Defense!!!

I had the best time at CrossFit One World. I was genuinely surprised by everything they have to offer from CrossFit, Yoga, Krav Maga classes to professional and personable coaches. I truly felt like I belonged to a community here and I could easily have a conversation with anyone in the gym! I have been to many CrossFit gyms across the country. No other CrossFit gym offers the an experience comparable to this one!

Don’t hesitate to spend your hard earned $$$ here. This place is awesome!!! Coaches are very supportive. I’ve lost 20 pounds on my first 6 weeks on bootcamp, and I feel 20 years younger😉. I’m on my first week in Crossfit, and I am so excited every time I go to class. Their techniques in every exercise are unique that I guess will give you the best results.

Went for a trial session in the morning. Although the coach was playing during our workout, he sounded aware of the TABATA work/rest times. I agree the gym has a good amount of floor space, but the coaching was not as per my expectation, so its not going to be my Crossfit gym. Thanks!

Amazing space for a Crossfit gym in the bay area, definitely the biggest in the tri-city! If you are looking to do olympic weightlifting, crossfit, self defense, etc. this is the place to be!
